Metasurfaces, acting as arrays of perfect nano-polarizers, provide a promising approach to manipulate the amplitude of an incident light at the sub-wavelength scale. In this Letter, we design and demonstrate continuous amplitude-modulated meta-fork gratings to generate optical vortex beams. More importantly, benefiting from the unique negative amplitude modulation, the unavoidable zero-order light that conventional amplitude-only elements always suffer disappears by carefully adjusting the orientation of each nanobrick. The dramati

Single Bed Bunk With Desk Bunk beds that have desks are great for kids rooms in which space is limited. They sleep high and save space on the floor for studying or playing which makes them a good choice for small bedrooms. To test bunk beds' wall-side guardrail and the end structure to ensure entrapment, insert the wedge block as shown in Figure 1.1, tapered side first, into each of the openings. Then determine whether it can be able to pass. Styles Bunk beds with desks can be the ideal solution for maximising th
